RIB FOR COTTQN-GINS.

dated July 3, 1883.

Application filed November 4, 1882. (No model.)

To all whom it may concern.-

Be it known that I, WILEY MERRITT, of Oovington, in the county of Newton and State of Georgia, have invented a new and useful Improvement in Ribs for Cotton-Grins, of which the following is a full, clear, and exact description.

The object of the invention is to make the wearing-plate used upon cotton-gin ribs adjustable, and this I accomplish by slotting the rib, forming a lug upon the wearing-plate, and employing a screw, as hereinafte described, and pointed out in the claim.

Reference isto be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicate corresponding parts in both the figures.

Figure 1 is a perspective view of :a cottongin rib with my improvement. Fig. 2 is a perspective vie of the wearingplate detached.

The rib A is of ordinary form, and at its upper side, and at the place where the sawteeth pass between the ribs, is the wearingplateB, the same being a crescent-shaped piece of metal fitting snugly upon the face of the rib, and attached thereto by a screw, a. is formed with a slot, b, and the wearing-plate I B is formed with alug, c, entering the slot, and the screw a passes through the slot from the under side of the rib and enters the lug This construction allows adjustment of i wearing-plate B up or down upon the r according to the wear. The wearing-plate can readily be removed when it becomes we to such an extent as to allow the seeds to p2 through with the lint and a new plate put place Without removing the ribs from the gi thus saving the expense of a new set of ri whenever they become worn so as to be un for use. The plates may be applied to a s of ribs that have already become so notcln and worn as to allow the seeds and motes pass through with the lint, and when appli in the manner shown the wearing-plate re] ders the ribs as good as new. When applie to a new set of ribs, the wear will be entire] upon the plates, which can be removed fro] time to time, as required.

Having thus described my invention, I clail as new and desire to secure by Letters Patent The plate 13, formed with the lug c and th attachingscrew a, in combination with the ii A, having the slot b, substantially as show] and described.
